This skit is for Devi & Harini and only they both can't play their own role so we have Sai as Harini and Lekha as Devi ... Why does Virat or someone else need to play Pulkit ? Apart from Devi- Harini, rest all can play their own part.. So i don't think there is any chance of Virat playing Pulkit.
Don't know why the assumption.. even the pic that choreographer shared had only Sai and Lekha in role play get up.. Neil was in white T-shirt which is his costume for the party which he wears under the brown coat.
Also in Precap, Pakhi is not interested in playing Devi.. had Virat been playing Pulkit, she would have happily accepted it..
I have issue with Pakhi playing Devi... not because Devi did not like her but because Pakhi never behaved humanly with Devi forget any other relation.. As Bk ill treated her, she too did the same. Pp never sympathized with Devi in fact she harmed her by writing that letter, even now defending Bk... If Pp doesn't have basic humanity towards devi.. How can she actually play her role and enact what Devi went through all this years? How did makers think that Pp can empathize Devi by role play???
